Definitions

  • This invention pertains to the field of articles for properly disposing of fat, oil, and/or grease ("FOG").
  • the invention relates to articles for preventing FOG from clogging pipes.
  • the kitchen is often a busy, hectic place where the stress of having to perform certain tasks within or at prescribed times is compounded by potentially dangerous activities, such as handling hot objects and liquids.
  • Properly disposing of common cooking byproduct FOG in its hot liquid form can be time-consuming and even dangerous.
  • handling and disposing of hot liquid FOG often entails the risk of spillage from and/or "jumping" in small quantities out of a cooking instrument, which can result in burns, damage to surrounding kitchen objects, not to mention create an additional mess.
  • waiting to dispose of FOG can be problematic because the FOG may cool, harden, and congeal to a cooking instrument (such as a frying pan), making cleaning and disposal more difficult.
  • FOG is unfortunately often poured in its liquid form down drains, where it flows into drainage pipes. Once in drainage pipes, the FOG cools, thickens, congeals, and sticks to the pipes, slowing water drainage, and eventually clogging and blocking flow altogether. This clogging and blogging causes substantial harm, such as destroying sceptic tanks, resulting in environmental damage (including soil and/or water contamination) and health hazards, emanating noxious smells, and attracting insects and pests. Conventional methods of removing FOG buildup in pipes are either unsatisfactory or costly.
  • an article for disposing of FOG may include a top portion comprising a top opening and a perimeter rim, and a body portion connected to and located below the top portion.
  • the body portion may include a continuous FOG-impermeable membrane, an upper body portion having a first maximum width, and a lower body portion having a second maximum width and a concave shape.
  • the body portion may include a body middle surface that divides the upper and lower body portions and may be configured for placement on at least a portion of a first bottom surface of a sink surrounding a first drain. The lower body portion may also be sized to fit within the first drain.
  • the interior of the body may also include FOG absorbent material.
  • the upper body portion may have a top maximum width contiguous to the top portion and a bottom maximum width contiguous to the body middle surface. In some examples, the top maximum width may be greater than the bottom maximum width.
  • the lower body portion may have an upper maximum width contiguous to the body middle surface and a lower maximum width defining a bottom of the body portion.
  • the upper maximum width may be greater than the lower maximum width.
  • the body middle surface may be flat.
  • the first drain may have a first drain maximum width that is greater than the second maximum width of the lower body portion.
  • the first drain may have a depth less than a height of the lower body portion.
  • the body middle surface may have a middle surface maximum width greater than the first drain maximum width.
  • the top opening may be defined by the perimeter rim.
  • the perimeter rim may be configured for placement on at least a portion of a second bottom surface of a second sink surrounding a second drain having a second drain maximum width.
  • the upper body portion may be concave shaped and sized to fit within the second drain.
  • the perimeter rim may have a maximum width greater than the second drain maximum width.
  • the second drain maximum width may be greater than the first drain maximum width.
  • the first maximum width of the upper body portion may be less than a second drain maximum width of a second drain sized to receive the upper body portion of the article. In some examples, the first maximum width may be greater than the second maximum width. In some examples, an exterior of the body portion may be defined by the continuous FOG-impermeable membrane.
  • a container for disposing of FOG may include an integrally formed continuous outer shell including an at least partially hollow interior, a top part having a top opening, a liquid impermeable bottom part, and a liquid impermeable upper part connecting and contiguous to both the top part and the bottom part.
  • the container may also include a middle part dividing the top and bottom parts and including at least one middle edge for placement of the container on a first surface surrounding a first drain.
  • the first drain may have a first maximum width
  • the bottom part may have a shape conforming at least in part to a hollow inner part of the drain for placement at least partially inside the first drain.
  • the outer shell may be configured to receive FOG through the top opening without the FOG exiting through the bottom part or the upper part.
  • the bottom part may include a second maximum width less than the first maximum width of the first drain.
  • the at least one middle edge may include a flat surface for placement of the container on the first surface surrounding the first drain. In some examples, the flat surface may have a third maximum width greater than the first maximum width.
  • the top part may include at least one top edge for placement on a second surface surrounding a second drain having a fourth maximum width.
  • the at least one top edge may include a rim having a fifth maximum width greater than the fourth maximum width.
  • the fourth maximum width may be greater than the first maximum width
  • the upper part may have a sixth maximum width less than the fourth maximum width and greater than the second maximum width.
  • the at least one middle edge may include at least two edges.
  • a method for disposing FOG may include positioning at least one edge of a container on a first bottom surface of a sink surrounding a first drain of the sink so that a top opening of a top portion of the container is facing upward, and at least some of a body portion of the container lies below the first bottom surface and within the first drain.
  • the body portion having a FOG- impermeable membrane.
  • the method may also include pouring the FOG through the top opening and into the body portion of the container, the container preventing the FOG from passing down the first drain.
  • the positioning may include resting at least two edges of the container on the first bottom surface. In some examples, the at least two edges may be located on different sides of the container. In some examples, the at least two edges may be located on opposite sides of the container. [0015] In some examples, the at least one edge may include a first perimeter rim. And in some examples, the positioning may include resting the first perimeter rim of the container on the first bottom surface. In some examples, the first perimeter rim may be located at the top portion of the container. In some examples, the first perimeter rim may be located at the body portion. In some examples, the body portion may include an upper body portion and a lower body portion. In some examples, the first perimeter rim may divide the upper body portion and the lower body portion.
  • the body portion may have a first maximum width
  • the first drain may have a second maximum width greater than the first maximum width.
  • the first perimeter rim may have a third maximum width greater than the second maximum width.
  • the container may include a second perimeter rim having a fourth (or second perimeter) maximum width greater than the third maximum width.
  • the method may further include resting the second perimeter rim on a second bottom surface of a sink surrounding a second drain.
  • the second drain may have a fifth maximum width less than the fourth maximum width.
  • the fifth maximum width may be greater than the second maximum width.
  • the body portion may have a concave shape, and the positioning may include positioning the at least one edge of the container on the first bottom surface so that at least some of the concaved shaped body portion lies within the first drain.
  • the interior of the body portion may include absorbent material.
  • the method may further include absorbing at least some of the FOG poured into the body portion using the absorbent material.
  • the FOG-impermeable membrane of the body portion may be liquid-impermeable.
  • the body portion may be connected to and located below the top portion. In some examples, the FOG-impermeable membrane may be continuous.
  • an article for disposing of FOG may include a perimeter rim defining a top opening configured for placement on the bottom kitchen sink surface surrounding a drain of the hollow inward type, so that the body of the article, into which FOG may be poured, lies below both the perimeter rim and the top opening and may generally (but not necessarily always) lie at or below a lower elevation than the bottom sink surface, and fitting within the hollowed inward part of the drain, the body comprising a shape for stably resting within the drain cavity, and for maximizing the body volume for receiving the FOG poured therein.
  • the article body comprising a shape conforming to and configured to stably fit within the hollow inward cavity of the drain
  • FOG may be poured into the top opening of the article where it may be stored rather than enter the pipe(s) of the drain.
  • the article perimeter rim in many embodiments may accordingly be circular, having a circumference wider than the top of the drain contiguous to the kitchen sink bottom surface.
  • the article body may comprise a membrane perimeter being made of liquid-impervious hard liner material or other rigid exterior membrane that is impermeable to liquid FOG.
  • Other embodiments may comprise an exterior membrane (i.e., membrane perimeter) that is substantially impermeable to liquid FOG.
  • the exterior membrane may by comprised of corrugated cardboard or recycled paper molded to the predetermined drain shape (molded for example utilizing a molded paper pulp process).
  • article embodiments may also comprise an interior section of absorbent material, for converting FOG absorbed thereby from a liquid or semi-liquid state to a solid or semi-sold state.
  • the absorbent material may be at least partly enclosed by the exterior membrane to prevent the FOG from passing through the (potentially oversaturated) absorbent material and into the drain pipes.
  • the entire lower interior of the membrane body may be filled with absorbent material.
  • Absorbent material may be configured to receive FOG through the top opening.
  • Said absorbent material may also comprise material(s) and designs (as described in more detail below) or other absorbent means for maximizing the amount of FOG capable of being absorbed given the limited body volume (or container size for embodiments comprising containers).
  • the FOG absorbent material in one embodiment may comprise polyurethane, and in one particular embodiment may also resemble a foam sponge comprised of cellulose material (such as wood pulp or other earth-friendly substance).
  • the entire article and/or the parts thereof may be disposable and/or biodegradable.
  • absorbent means with the FOG converted from a liquid state into an at least semi-solid state, the container may be placed in the trash with less risk that puncturing of the container will result in the FOG contents leaking into the remainder of the refuse.
  • the article may also comprise additional features for maximizing FOG absorption, such as in one embodiment a cover for placement in the top opening for distributing the FOG poured thereon in a predetermined manner over the absorbent material in order to increase FOG saturation of the absorbent material.
  • Said cover in one embodiment may have a radially positioned array of slotted annular openings for distributing liquid over the absorbent material, the slots being of narrow width to keep the trapped and congealed FOG contained within the body for disposal.
  • some body embodiments may comprise an interior adsorbent surface (which in another embodiment might comprise a removable liner made of, for example, aluminum foil or heavy paper such as wax paper).
  • the article may comprise a predetermined size and/or body volume (and amount of absorbent material) for holding an amount of FOG cooking byproduct tailored to a single instance of home cooking.
  • the body may have a volume for holding substantially four ounces of FOG and absorbent means configured to receive FOG in a maximum amount within the body volume.
  • a size intended for optimally-efficient one-time use, without requiring additional instances of usage, to efficiently utilize and not waste container material, may allow a user to omit burdensome and time-consuming disposal steps, such as storage, sealing and unsealing a lid multiple times, and placing the container in a refrigerator or freezer.
  • the exterior membrane of the body configured for placement in the hollowed inward portion of the drain is rigid (for among other benefits preventing hot liquid FOG poured thereon from compromising the figure of the membrane) and forms a container that stably rests in the drain while FOG is poured into the container through the top opening, with the container sides not stretching substantially above the level of the kitchen sink bottom surface, thus allowing a cooking instrument from which the FOG is poured to be held at a lower elevated and more advantageous position.
  • the exterior membrane comprises a rigid outer shell for receiving, holding, and disposing of FOG, which may be separable from the portion of the article comprising the absorbent means.
  • the FOG absorbent or adsorbent means may be disposed of without the rest of the article also having to be thrown away.
  • the entire article may be designed for convenient disposal along with the FOG absorbent/adsorbent means.
  • the shape of the body configured for placement in a drain may also provide greater stability and less awkward handling while pouring FOG.
  • the body may comprise an inside surface that may be continuously downward sloping, to facilitate continued downward flow of FOG due to gravity and filling of the lowest part of the interior of the container first, or to otherwise strategically pass liquid FOG to the section of absorbent material.
  • the FOG may be poured therein with less risk of spilling, until at a maximum the FOG absorbent means has been fully saturated and/or until an adsorbent means has also reached its full capacity.
  • the article body may comprise a rigid, flat bottom surface for placement of the container on another flat surface, such as a countertop, with less worry of the FOG spilling.
  • the flat bottom surface may have a width of substantially 2.6 inches.
  • Some embodiments may also comprise other features for more convenient and/or safer handling of the article, such as a perimeter rim comprising legs or knobs or other means for holding the rest of the perimeter rim elevated sufficiently above the bottom surface of the kitchen drain surface (yet still not substantially above the kitchen drain bottom surface) to facilitate grabbing with fingers and removing the article from the drain once the FOG has been poured therein.
  • a perimeter rim comprising legs or knobs or other means for holding the rest of the perimeter rim elevated sufficiently above the bottom surface of the kitchen drain surface (yet still not substantially above the kitchen drain bottom surface) to facilitate grabbing with fingers and removing the article from the drain once the FOG has been poured therein.

  • non-rigid and thin container membranes may also either be melted or deformed by hot liquid FOG and/or bent out of shape by the weight of FOG poured thereon or by external objects.
  • containers/bags with non-rigid membranes are more likely to take the shape of the inside liquid contents, and therefore may be awkward to handle, increasing the likelihood of spilling.
  • the risk of spilling is even greater when/if the bags are not sealed fairly soon after FOG is placed therein.
  • the lack of a substantially rigid membrane increases the likelihood of the FOG leaking and spilling through breaches in the seal.
  • containers/bags with thicker and more impervious membranes are generally more costly to produce. Since these costs are normally passed onto consumers, and prior art containers/bags holding congealed FOG must normally be disposed of along with the FOG, it may be impractical for cost-conscious consumers to regularly use and dispose of such more expensive containers/bags. In addition to higher costs, many such containers/bags with thicker less pervious membranes (and even those with thinner, more pervious membranes) are less biodegradable and therefore more harmful to the environment. For example, although some containers might be recyclable when not contaminated with FOG, the congealed and sticking FOG may foreclose such functionality, which may result in additional environmental harm (especially where the container is not biodegradable).
  • containers/bags appear to be designed to hold approximately one quart of FOG or more, yet the FOG byproduct from one non-commercial cooking session is often much less than a quart. It is not uncommon, for example, that one instance of home cooking generates an amount of FOG byproduct not substantially more than four ounces, and in a range of two to six and a half ounces. Regardless of the precise amount of FOG byproduct generated, the larger containers/bags must often be reused several times before disposal in order to avoid waste of container material, and thus require additional and time-consuming steps relating to such reuse.
  • Such steps include, for example, in the interim between each addition of FOG by product from different instances of cooking, the proper storage of both the FOG and container, during which time bacteria and pests may be attracted and/or unpleasant odors emanated.
  • a FOG-holding container/bag is often either placed in a refrigerator or freezer, thus requiring additional space, attention, and time, or sealed, for example, with a removable lid, and then unsealed when more FOG is placed therein, which sealing and unsealing requires additional time.
  • hot "liquid" FOG may include lumps, ash, or even small food particles, which inconsistencies can result in irregularities in flow when pouring.
  • FOG may be created in various cooking instruments that are not conducive to pouring in a precise manner, such as cooking pans with gradually curved rims and flat edges (i.e., without spouts or other features for focusing or directing flow of a liquid).
  • the handle(s) of such instruments may not have been designed to provide optimal leverage, vantage point, or control for pouring.
  • the FOG may normally be poured by holding the pan away from the body with the arm outstretched, and slowly tilting a side of the pan towards the container and attempting to monitor the flow of liquid with the naked eye.
  • This challenge of controlling pouring the FOG is often exacerbated (whether or not consciously recognized by the person pouring) by an often-raised position of the container/bag due both to placement on elevated kitchen countertops and the large sides of the such prior art container/bag that create an elevated container/bag top opening that may even be higher above the kitchen countertop level.
  • This elevated position of the "point of entry" for the pouring of the FOG may require that the FOG-pouring cooking instrument (e.g ., the pan) be held by the arm(s) and hand(s) in an even more lofty and harder to control position.
  • Described herein is such an article for disposing of FOG that overcomes one or more of the aforementioned challenges, such as those associated with substantially non-rigid membranes (which may lead to awkward handling, spillage, and bending/disfiguration of the membrane at the point of FOG contact), having to pour FOG from an elevated position into an elevated point of entry (i.e., opening) of a container/bag, wasting container material, requiring time-consuming steps, being prohibitively expensive (when disposing a container after each session of FOG-generating cooking), not maximizing FOG saturation of absorbent material, and not being environmentally friendly.
  • Said article for overcoming one or more of such challenges may provide consumers among other benefits an attractive alternative and practical solution to pouring FOG into a drain (where it can cause environmental harm).
  • the relative convenience of securely placing the article in the hollowed portion of the drain of the kitchen sink may encourage proper disposal instead of pouring FOG down a drain and serve as an effective reminder to a user to not pour the FOG down the drain.
  • the stabilized position for holding the container within the hollowed inward drain while FOG is poured therein, without requiring use of other supporting devices (such as a funnel) or stabilization by a person's hand(s), may allow a person to use both hands to carefully pour the FOG into the article.
  • the placement of the article in the substantially lower-elevated position of the drain, furthermore, such as that found along the floor of a kitchen sink, may allow a person to more easily and in a more controlled manner hold a pan or other cooking instrument at a lower point over the container, thereby avoiding the expenditure of greater energy and allowing more control.
  • Pouring at a level below the countertop level and/or substantially at the surface of a kitchen sink may also be advantageous in the event that hot liquid FOG "jumps" from a container or pan.
  • the sides of a kitchen sink may also act more effectively as protective walls preventing the FOG from causing injury or damage or mess outside the sink area.
  • the vantage point of looking down into the article in the drain, and of standing in closer proximity to the container may also assist in careful pouring without spilling.
  • the size of the top opening of the article may be substantially equal to the width (or diameter) of the drain opening, thereby providing a sufficiently large "target” for pouring the FOG into (when compared to the more narrow openings of some conventional containers).
  • the top opening of some article embodiments may not be substantially wider than the drain opening diameter or substantially elevated above the kitchen sink floor surrounding the drain, the article may be placed in the drain without substantially encumbering the area above or around the drain (and especially without encumbering said area with potentially unused container volume), which area might instead be more easily used for careful manipulation of a cooking instrument holding and/or pouring FOG.
  • the top opening may close after FOG is poured therein, and may be resealed, and in other embodiments may be reopened and resealed according to user preference.
  • the article exterior membrane may also comprise supporting bars to provide additional structural support, which may further assist in retaining intended shape without requiring a thicker exterior membrane. It is further anticipated that the article may comprise material, in one embodiment, that is not only impervious to hot liquid FOG, but may also comprise on the outside heat absorbing material, allowing grabbing and holding without risk of burning a person's hand.
  • FIG. 1 illustrates a first article embodiment 13 for disposing of FOG, in accordance with various aspects of this disclosure.
  • the article 13 may comprise absorbent material 14 contained by an outer body perimeter (i.e., exterior membrane forming a body shape) 16, and a top opening 15 above the absorbent material 14 for receiving FOG there-through, the top opening 15 defined by a perimeter rim 17 having a width wider than the body perimeter 16.
  • FIG. 2 is a top perspective view of the article of FIG. 1, in accordance with various aspects of this disclosure.
  • the article 13 may also comprise a cover 18 for placement over both the top opening 15 and the absorbent material 14 thereunder.
  • the cover 18, in the embodiment 13 shown, when placed over the top opening 15 defined by the perimeter rim 17, may comprise a design for distributing FOG 19 more evenly over the absorbent material 14.
  • FIG. 3 is a cutaway cross sectional view of the article of FIG. 2 placed in a drain of a kitchen sink, in accordance with various aspects of this disclosure.
  • the perimeter rim 17 may comprise dimensions and/or have a shape adapted for placement on the bottom kitchen sink surface 21 surrounding a drain 22 of the hollow inward type, so that the article body 16 (or some portion thereof), more narrow than and below the rim 17, may fit within the drain cavity 20 and stably rest therein.
  • the body 16, moreover, may comprise a shape conforming to, the hollow inward cavity of the drain 20 and configured for maximizing the amount of absorbent material 14 and available volume for receiving the FOG 19 therein.
  • the drain 20 shown like drains often found along a bottom kitchen sink surface 21, comprises circular ring-shaped cross sections.
  • the perimeter rim 17 of the article embodiment 13 shown may also be circular, having a circumference greater than the circumference of the top of the drain 23 (contiguous to the kitchen sink bottom surface 21) for placement thereon, and the body 16 also may also have circular cross sections of sizes for securely placing the article 13 within the concave drain 20.
  • the top opening 15 defined by the perimeter rim 17 may also have a circumference and/or width substantially approximating the circumference and/or width of the top of the drain 23, thereby providing a larger "target" for pouring the FOG there-through.
  • the combined width of the top opening 15 and the perimeter rim 17 may be in the embodiment shown substantially 4.4 inches.
  • the height of the perimeter rim 17 in the embodiment shown may substantially be 0.75 inches, or other height so that the top opening 15 is not substantially above, or rather substantially even with the level of the bottom sink surface 21.
  • the height from the top of the perimeter rim 17 to the bottom of the article 13 may in the embodiment shown be substantially 2.38 inches.
  • the body 16 may also comprise an inside surface 24 bordering the absorbent material 14 that is continuously downward sloping, and may in the embodiment shown have a pitch of substantially 18 degrees, to facilitate continued downward flow of FOG 19 so that the absorbent material 14 is more likely to become saturated first from the bottom up. In this manner, pouring FOG 19 into the top opening 15 prevents and provides an attractive alternative from FOG 19 being poured down the drain 20 and entering a pipe 22.
  • FIG. 4 is a cutaway cross sectional view of the article of FIG. 3, in accordance with various aspects of this disclosure.
  • the absorbent material 14 in the particular embodiment shown 13 may have a sponge-like texture (may comprise polyurethane), and may convert the liquid FOG 19 absorbed thereby to a solid or semi-sold, more stable state 25.
